Understanding the Need to Stop Anticoagulants Before Surgery
ELIQUIS (apixaban) is a direct oral anticoagulant (DOAC) that inhibits factor Xa to prevent blood clots. Stopping this medication before surgery is essential to prevent excessive bleeding. Hip fracture surgery is often urgent, and while guidelines exist for holding anticoagulants, delaying surgery can lead to complications. The approach involves balancing the risks of bleeding and surgical delay.
Factors Influencing the ELIQUIS Hold Period
Several factors determine how long ELIQUIS should be held:
- Bleeding Risk: Hip fracture surgery is a high-bleeding-risk procedure. The standard recommendation is to hold ELIQUIS for at least 48 hours.
- Renal Function: Impaired kidney function affects how quickly ELIQUIS is cleared from the body, requiring longer hold times. For moderate impairment, 72 hours or more may be needed, while severe impairment could require 96 hours or longer.
- Reason for Anticoagulation: The patient's underlying condition for taking ELIQUIS influences the risk of blood clots if the medication is stopped.
The Urgent Nature of Hip Fracture Surgery
Delaying hip fracture surgery is associated with increased risks of complications and mortality. While standard hold times are recommended, some studies suggest that earlier surgery might be safe under specific protocols. A multidisciplinary team approach is vital for making decisions in urgent cases, especially when considering renal function and delaying surgery.
Comparing Hold Times Based on Clinical Factors
Clinical Factor | Recommended ELIQUIS Hold Time | Rationale |
---|---|---|
Standard (Normal Renal Function) | At least 48 hours before a high-bleeding-risk procedure like hip fracture surgery. | This period allows for sufficient clearance of apixaban from the blood in most patients with healthy kidneys. |
Moderate Renal Impairment (CrCl 30–50 mL/min) | 72 hours or longer, depending on specific hospital protocol. | Reduced kidney function prolongs the drug's half-life, meaning more time is needed for the anticoagulant effect to diminish. |
Severe Renal Impairment (CrCl <30 mL/min) | Up to 96 hours or more; a hematology consultation is typically required. | The risk of drug accumulation and bleeding is much higher, requiring a more cautious approach and expert consultation. |
Neuraxial Anesthesia (Epidural/Spinal) | 72 hours before the block. | This is a specific safety guideline from the American Society of Regional Anesthesia and Pain Medicine (ASRA) due to the risk of spinal hematoma. |
Managing Anticoagulation in an Emergency
In emergency situations where standard hold times are not feasible, a multidisciplinary team will assess the risks. For life-threatening bleeding, a reversal agent for apixaban, such as andexanet alfa, may be used. The decision to proceed with surgery earlier than the standard hold time is made based on balancing bleeding risks and the risks of delaying surgery.
Resuming ELIQUIS After Surgery
Resuming ELIQUIS safely after surgery is as important as stopping it. It is typically restarted 12 to 72 hours post-surgery once bleeding is controlled. The timing depends on the risk of bleeding after the procedure and the individual's risk of blood clots. Protocols may vary, and resumption should be guided by the medical team. Information on resuming ELIQUIS and perioperative management can be found from sources like the American College of Cardiology.
Conclusion
Determining how long to hold ELIQUIS before hip fracture surgery requires careful consideration of bleeding risks, renal function, and the urgency of the procedure. While a 48-hour hold is standard for high-risk procedures with normal renal function, individual patient factors and the need to avoid surgical delays in hip fracture cases necessitate a tailored approach. Multidisciplinary consultation is key to optimizing patient safety. Always follow your healthcare provider's specific instructions for managing your medication around the time of surgery.
